【摘要】:當(dāng)前,,以高血壓和冠心病為代表的心血管疾病,正日益成為人類健康的首要威脅。同時,飛速發(fā)展的無線網(wǎng)絡(luò)通信技術(shù),已經(jīng)引發(fā)了一場新的信息化革命。以此為契機(jī),以專業(yè)醫(yī)院為主體的舊有醫(yī)療模式,正在向以社區(qū)和家庭為主的開放式新型醫(yī)療模式轉(zhuǎn)換。在這種形勢下,研究和開發(fā)以無線移動式平臺作為醫(yī)學(xué)信息載體,針對多種人體生理參數(shù),實(shí)現(xiàn)健康和疾病診斷的便攜式、智能化監(jiān)測儀器系統(tǒng),可以為心血管疾病的早期診斷和預(yù)防,提供全面、快捷的解決方案。 人體生理參數(shù)主要包括心電、心率、血壓、血氧和體溫等。心臟作為人體血液循環(huán)的動力器官,以心動周期為節(jié)拍,重復(fù)完成心室的收縮和舒張過程。目前臨床使用的心電ECG檢查和動態(tài)心電監(jiān)測(Holter),使用的均是氯化銀(AgCl)濕性電極,它通過電解液凝膠體與皮膚接觸來傳導(dǎo)微弱的心電信號,但其毒性物質(zhì)會滲透到皮膚中造成過敏性皮炎,而且在長時間使用后,電解液凝膠體因脫水而干化,造成電極與皮膚之間的接觸阻抗發(fā)生變化,導(dǎo)致信號靈敏度和信噪比下降。此外,基于柯氏音聽診法的袖帶充氣式血壓測量,除了束縛使用者的日;顒右酝,當(dāng)壓力袖帶工作時,會對患者造成突然性刺激,由心理變化產(chǎn)生情緒波動,導(dǎo)致測量結(jié)果失準(zhǔn)。 針對以上問題,論文以生命科學(xué)、計算機(jī)科學(xué)、現(xiàn)代通信技術(shù)和儀器科學(xué)為基礎(chǔ),研究了一種基于移動通信平臺的人體生理參數(shù)監(jiān)測系統(tǒng),實(shí)現(xiàn)對心臟病和高血壓等心血管疾病的早期診斷和預(yù)防。該系統(tǒng)由穿戴衣載體、紡織心電電極、指夾式脈搏波傳感器及其測量電路,構(gòu)成基本的心電和血氧飽和度的穿戴式測量單元,并通過對心電和脈搏波信號的波形參數(shù)進(jìn)行回歸計算,實(shí)現(xiàn)無袖帶的收縮壓和舒張壓的動脈血壓測量。另外,基于PDA構(gòu)建了移動式用戶手持終端,通過藍(lán)牙接口,與測量單元構(gòu)成人體軀域監(jiān)測網(wǎng)絡(luò),完成心電和脈搏波數(shù)據(jù)的接收、波形回放顯示,以及對血壓和血氧飽和度等生理參數(shù)的計算。 論文研究的主要內(nèi)容包括: 1、完成系統(tǒng)總體結(jié)構(gòu)設(shè)計。具體包括心電調(diào)理模塊、血氧測量模塊、微處理器單元、藍(lán)牙傳輸模塊的實(shí)現(xiàn),并進(jìn)行信號濾波電路的設(shè)計,有效地保證了后續(xù)信號的處理。 2、通過對移動終端的構(gòu)建。實(shí)現(xiàn)人體心電和脈搏波數(shù)據(jù)的實(shí)時接收、波形回放顯示,以及對血壓和血氧飽和度等生理參數(shù)的計算。 3、實(shí)現(xiàn)了系統(tǒng)的軟件設(shè)計。完成了用戶手持終端的軟件設(shè)計,通過設(shè)計數(shù)字濾波器,對心電信號進(jìn)行了濾波處理。 4、進(jìn)行血壓和血氧飽和度的測量。通過對心電和脈搏波信號的波形參數(shù)進(jìn)行回歸計算,實(shí)現(xiàn)了無袖帶的血壓測量;針對監(jiān)測系統(tǒng)的設(shè)計要求和血氧飽和度的測量狀況,提出基于光譜監(jiān)測原理來實(shí)現(xiàn)血氧飽和度的無創(chuàng)測量。 5、實(shí)驗(yàn)測試。應(yīng)用監(jiān)測系統(tǒng)進(jìn)行實(shí)驗(yàn)分析。首先對測試者進(jìn)行收縮壓的參數(shù)標(biāo)定,通過標(biāo)定實(shí)驗(yàn),證明了收縮壓可以通過脈搏波傳導(dǎo)時間直接近似計算;其次應(yīng)用標(biāo)準(zhǔn)袖帶血壓計來對監(jiān)測系統(tǒng)進(jìn)行儀器的一致性分析,實(shí)驗(yàn)結(jié)果表明,使用該監(jiān)測系統(tǒng)可以替代標(biāo)準(zhǔn)袖帶血壓計進(jìn)行血壓測量。
